On torch extraction
May 1st 2008

The dangers of fumes from welding have long been known. Fumes can damage the nervous system and respiratory tract, as well as having other adverse effects

Traditional capture hoods and nozzles can work well, but require an element of operator involvement to ensure correct positioning of the capture device.

For MIG Welding it has been possible to integrate the capture nozzle into the welding torch itself, and advances in recent years have seen these torches improve in efficiency, weight and manoeuvrability.

Having the extraction device built into the torch removes responsibility from the welder to position hoods or nozzles correctly, as the point of extraction is always in proximity to the weld.

Until recently the efficiency of on torch fume extraction had not been tested, and there were certain questions of doubt over the overall effectiveness of such systems.

Nederman, together with their partner Abicor Binzel commissioned tests at the Health & Safety Laboratory that would answer such questions and for the first time provide quantative results of capture efficiency via the welding torch. A welding torch was connected to a Nederman High Vacuum System, and the tests took into account a range of welding positions and parameters.

The report has concluded that the extraction of welding fumes via the torch can offer very high capture efficiencies and with the correct welding parameters in place, there was no disturbance of shielding gas and therefore no detriment to the integrity of the weld. The advantage of a Nederman high vacuum system as the power source to on torch extraction is that the same system can extract from workshop tools, such as sanders and grinders, and can also be employed for floor and general cleaning work.

Nederman will be pleased to supply you with a free copy of this report. To obtain your copy please telephone our customer support on 01772 334721. We will also be pleased to offer an on site demonstration of on torch fume extraction at your premises, or alternatively arrange for you to see and try out this process at our demonstration area at Preston

Dust & fume extraction – summer special offers

To inhale fresh air and have a clean workplace is what we all want. Airborne dust and fumes come in many forms, they can be poisonous, or an irritant, some forms of dust can even be explosive. In whatever form these pollutants are encountered, they present a problem that has to be dealt with.

Nederman P160 portable units are light weight extraction systems ideal for cleaning, on tool for processes such as grinding, sanding, buffing, polishing and also general factory workshop clean up, and on torch extraction from welding processes.

Working with products such as composites, plastics, fibreglass wood and various metals, produces dusts and fumes which require effective capture and extraction from your working area.

The Nederman Summer offer (valid until 31/8/2008) will provide you with a complete solution to either on tool or on torch extraction. Each package includes the unit - together with various accessories. You will receive either a welding torch, or a sander, dependent upon which package is purchased. The On Torch package is £975.00 plus VAT, and the On Tool package is just £995.00 plus VAT.

We can also provide a free on site demonstration at your premises. For further information, or to arrange your free demonstration contact our Sales Support on 01772 334721.
